13? Guys were TUPE’d Sept 1st, so 7 months.
The courts have no specific recognised time period.
If the company had more pilots than they required then surely the appropriate procedures should be followed, ie. ‘Last in first out’, continuous employment means that these guys went across with CHC start dates and are probably longer serving than quite a few original BHL guys.
Because their actions aren’t due to an excess in pilot numbers and merely to get these fella’s onto a more convenient contract, convenient to management, I’d be surprised if this didn’t have grounds for unfair dismissal. Get a decent employment lawyer, BHL would run to the hills. Or even better than that, don’t go back when they offer the new Ts&Cs - their loss.
