Express was the first experience I had in that an employer could deny holiday pay for calling in sick the day before or after the holiday. I understand the reason for the policy, it just could never find any rationale that would stand legal muster that would allow them to do so.
From memory, they also can deny holiday pay if an employee is late either the day before or day after a holiday. Again, I could never find any justification that would stand legal scrutiny for this policy.
Just more reason for you guys to organize...
