One of my employees is doing a distance learning course which involves 2 x 2 week residential trips a year. Our agreement is that I pay the course fees, but would it be usual for an employer to pay for all travel expenses plus accommodation? Due to the distance involved I can see this easily adding up to £1k per trip.
Depends. Is it a course you are effectively sending her on, or has she decided to do it and asked for sponsorship?
If the former, then yes you pay. If the latter, then it's for negotiation between you. Has she started it already and only just found out/told you, or is this all being discussed upfront before she commits to the course?
