The nation will no doubt be on the edge of its seat tonight as England play Mexico at the Azteca. After a number of touch and go matches with two late game goals from Harry Kane against the Democratic Republic of Congo, it’s no surprise that both the captain and England manager Thomas Tuchel has urged home fans to keep up the support.Especially as El Tri has the advantage of familiarity at the Mexico City stadium with its high altitude of more than 2,000 metres above sea level - and have yet to concede a goal this tournament.But with the match starting at 1am on a Monday, and the prospect of it going on until 4am if it goes to penalties, workers who choose to watch the match may not have much opportunity to sleep before their alarm goes off the next day.Pubs will be allowed to open later, and schools across the country have said they will allow pupils to start late on Monday so that they can watch the match in the early hours.

Those who only realised England would be playing the late night match after the DR Congo win have had a lot shorter notice to take annual leave.Nicole Humphreys, a partner at the solicitors Mayo Wynne Baxter, told The Guardian you have no automatic right to take time off at short notice for a match. “Many employers will have policies setting out how holiday should be booked. Where there is no policy, employees should usually give notice of at least twice the length of the time off they are requesting.”People who took the annual leave off as soon as possible - and managed to get it approved - will fare better than those who waited last minute. Those who take the Monday off without permission may face disciplinary action.England’s manager has urged fans to support the team ahead of the challenging match against El Tri (Getty)Calling in sickAfter England played DR Congo at 5pm last Wednesday, industry experts expected a rise in sick calls on Thursday. Alan Price, from BrightHR - which provides HR software and advice and works with 68,000 small businesses in the UK - said his company saw a five per cent increase in employees that booked time off from their systems for the Wednesday match.Employment rights allow people to self-certify their illness for up to seven calendar days without a doctor’s note or fit note. Experts have warned employers against jumping to conclusions for those who call in sick for this match, although companies may investigate if they have suspicions.Joanne Moseley, the legal director at the law firm Irwin Mitchell, told The Guardian: “Employers should already have processes in place to deal with staff who phone in sick for the odd day.“These usually start with a return-to-work interview where they should be asked to explain any inconsistencies between the reason given for their absence and any observed behaviour – such as pictures of them on social media watching football in the pub.”Pubs will now be able to open until 5am on Monday morning (PA)Arriving lateIt is up to employer’s discretion to allow you to work flexibly on Monday. People who have not previously agreed with their boss that they’ll be late could be marked as absent without authorisation.TUC general secretary Paul Nowak, supporting England in the World Cup, has encouraged employers to be more flexible ahead of the Mexico match.“World Cup fever has gripped the UK, with millions of workers across the country cheering on the Three Lions,” he said. “The timing of England’s match against Mexico is not ideal for fans. That’s why we are appealing to employers to show some common sense and understanding by allowing their staff to work flexibly where possible.“That could mean letting them start later on Monday or swap their hours,” he added. “I’ll be cheering on my team – as will workers up and down the country. Come on England!”
