Seasonal, if your looking for a year round stable job. Although it's only about 5 months of the year where seasonal work isn't offered in some form from the company (not necessarily in just vernon)
Piece rate may be a downfall if you aren't yet skilled in certain ways such as physical fitness, or for the summer months while thinning, mental agility and dexterity.
Outside temperatures. Some mornings are ice cold, and during the summer I was arriving to start thinning for the day at 5 am, 2 hours sooner than expected, to beat the heat as it gets unbelievably hot in the day.
Got a lot of bruises from accidentally walking into steal beams in the spring but that's a force that can be wreckened with easily, I believe. it happens.
Often it can take some adjusting to the pace when your new, but given a few months, or often alot less time, your muscle memory will have your back and you'll become natural at it.
With the seasonal positions, you sometimes wont work consecutively enough to make the union, as in for a span longer than 3 month before layoff. but I believe it will start after 3 months in the summer if you take all earning opportunities.
