If you are a Thomsonfly FO Call your Balpa rep asap.
No need to do so. No more DEC at Thomsonfly, enough internal candidates apparently. Contract skippers not ideal, however much better as an interim measure than lots of DEC appearing at the bottom of the seniority list.
Incidentally, until recently the internal candidates had a much more onerous assessment to pass than a mere 2 days of HR B/S.
