Examples in context

‘Can work make me cancel annual leave at the last minute?

When you’ve spent months looking forward to spending some quality time away from the office, it can be gutting to realise your well-laid plans may be turned upside down at the last minute.

While planning successfully for this should be the responsibility of company management, unexpected new projects can always throw a spanner in the works, creating last-minute staffing needs. It’s important to note that employers do have the right to tell their staff when to take leave, and to ask employees to postpone leave already arranged.’

‘Team of former Manchester United stars have mansions on market - but no one’s biting

A squad of former Manchester United stars have put their multi-million pound mansions on the market.

As the current team comes under fire for their poor form and boring style, fans could be forgiven for casting an envious eye at some of the players who have departed.

But while the exclusivity is part of the lure for the big-earning and big-spending footballers, it can throw a spanner in the works when they try to sell up.

The mansions boast everything a millionaire player could ever want - with features like gyms, cinemas, games rooms, swimming pools and even stables.’
